Displaying image from text

Hi
I want to display a image in a JTextArea.
If I type in the letter A in my JtextField then I want to display a image my replaceing the letter.....
how would i do this....does someone have a example?????
Thanks
Dilip

image in a JTextArea.That's not a great idea. You're better off using a label with an image icon.
how would i do this....First, create an (empty) image. Then get its graphics and paint the letter into it. Finally, refresh your label.

Can anyone help me plz?
Thnx in advance.

Hello,
It is very difficult for us to "guess" what images you can read and what others you cannot.
Maybe you could provide more information on images that are not displayed ?
What is their native format ?

My iphone 4s suddenly displays images from Yahoo, Google, and Flickr at low resolution. The camera on my phone works fine, but any web related photo content is now pixelated and low res, what's the deal?

My iphone 4s suddenly displays images from Yahoo, Google, and Flickr at a low resolution. I have IOS 7.0.4. My phone camera works fine, but any web based photo content from Safari, Yahoo images, Google images, and Flickr all come in pixelated and low res. What's the deal?

It happened to me but later I figured out that cellular signal was not that great and so the Internet was very slow. It took me about 2 minutes to get the full resolution picuture on either of the app you've described. Try to get faster internet either by wifi or good signal and then check.

Display Images from HTMLDB_APPLICATION_FILES Table?

How do I display images from the HTMLDB_APPLICATION_FILES Table?
Are the contents full available potentially for display? Or only after I have written them to another display?
Please advise what I need to do or what corrections below is required:
The calling procedure is a item in a SELECT statement as part of a report query:
<P>
<(img src="#OWNER#.download_HAF_file?p_file= ' || nvl(ID,0) || ' height="50" width="50" )>, HAFimg<P>
The Procedure is a adaptation of the Chapter 8 Exercise of the 2 day developer guide:

I believe you put HTML "pre" tags around your quote (with square brackets, I can't type them here because they'll be escaped).
If the example below looks formatted then using "pre" works, if not...then ignore me ;)
begin
select
    count(*)
into
    v_count
from big_table;
end;

Display images from a SQL database

I want to display images from a SQL database. The images are in a table under a specific column and are stored as a link to the image. How would I display the images from the column in LabVIEW?
I'm using LabVIEW 2013 version 13 and SQL Server 2012
Paul Power
I have not lost my mind, it's backed up on a disk somewhere

Hi PauldePaor,
I hope you are well.
Once you have pulled the data from the database into LabVIEW in a string form (or path), you can simply use the Read BMP File (Or jpg, png depending on the file type) VI.
More information can be found here:

How to display images from BLOB column via APEX 4.0

Hello,
I did the following in order to display images of two Oracle records on the APEX page. I am using APEX Version : 4.0.1.00.03 , Oracle DB Version : 10.2.0.4.0.
1. Created An oracle table TEST_FORM
with 3 columns
( ID number, MIME_TYPE varchar2(255) , Image BLOB )
2. Inserted two records
10001, image/gif, ( actual image1)
10002, image/gif, ( actual image2)
3. created an Oracle procedure
CREATE OR REPLACE PROCEDURE show_my_form ( p_image_id IN test_form.id%type) AS
l_mime test_form.mime_type%type;
l_length NUMBER;
l_file_name VARCHAR2 (2000);
lob_loc test_form.IMAGE%type;
BEGIN
SELECT mime_type, IMAGE
, DBMS_LOB.getlength (IMAGE)
INTO l_mime, lob_loc, l_length
FROM test_form
WHERE id = p_image_id;
owa_util.mime_header(l_mime, false);
htp.p ('Content-length: ' || l_length);
owa_util.http_header_close;
wpg_docload.download_file (lob_loc);
END show_my_form ;
4. In Apex 4.0
step1. Created an interactive report on a new APEX page
step2. Specified the following in the Region Source
select id, mime_type, '<img src="#OWNER#.show_my_form ?p_image_id=#ID#" />' photo
from TEST_FORM
The column result shows as <img src="CCS.show_my_form?p_image_id=#ID#" />
I am unable to display the column image as a link to a proper image photo.
Could you please advise me if I missed anything ?
Thanks a lot.
Regards
Susanna

Maybe the space you have before the ? is causing issues. there shouldn't be any space.
Your procedure looks to be much the same of one that I have.
Have you granted execute on your procedure?
Also, what version DB are you running? This could be another issue: http://daust.blogspot.com/2006/04/xe-calling-stored-procedures.html
But anyway, you don't need to create your own procedure these days. You could do the following:
in your query, have a column: dbms_lob.getlength(blob) photo ; save, then in column attributes for that column, apply a format mask. There is usually a link below the text box for the format mask - BLOB Download Format Mask, which will help you build the format mask. But it is documented here: http://download.oracle.com/docs/cd/E17556_01/doc/user.40/e15517/advnc.htm#BCGGJHEF

Displaying image from Database with php

Hello everybody,
I'm working on a website that displays videos courses and tutorials as my final project
and I'm working with "Flash builder 4" the database with mySQL and the application server with php
Basically, the goal is to display a datagrid that shows the manager of the website in column all the information stored on the "Course" table
the structure of the table is :
Course (id,img,src,title,description)
-id : primary key
-img : path to a photo of course {for example picture of JAVA}
-src : path to the playlist file {xml file}
-title : String
-description : String too
I already succeeded to display all these contents on a DataGrid, but not with the image, I couldn't display an imageon its column using the path stored on the database, I used a DataRenderer to do that, and here is my code for Renderer and the DataGrid.mxml
CourseGrid.mxml

Result :
Problem :
How can I access to the path of the image, I tried to write "data.img" instead of "data" as img is the name of the column in the database that stores the path but it wasn't successful.
I know that it not complete statement "data" because "data" is a reference to what the DataGrid provides of information that gets from the (CreationComplete) event.
Question :
- Can you please help me with this so I can complete displaying images by accessing to what is on the column in tha DB so I can manipulate my datas that is stored there ?
==> I still have some questions about the buttons to update and delete datas fomr the DataGrid, but, until now I need to access successfully to the photo and display it
Thank you,

Anyone that can help me with this ?
Please, try this with me, I'm asking Flex developpers this might be easy for you !
It's just question of how to access the string stored in the variable "data", when I used XML I just type the path to the repeated element like this :
XML file :
XML File
<parent>
<child>
<repeated_child></repeated_child>
<repeated_child></repeated_child>
<repeated_child></repeated_child>
</child>
</parent>
I used a Model as a reference to the xml file
and an arrayList as a container of the repeated child
I just write in the code "data.parent.repeated_child" to access the text in the "repeated_child"
and here is the code, that I implemented to generate videos from xml file to display a video play list
Video Playlist code(extract from XML file "data.xml")
<fx:Declarations>
<fx:Model id="model" source="assets/data.xml"/>
<s:ArrayList id="products" source="{model.video}"/>
</fx:Declarations>
<mx:List dataProvider="{products}" labelField="title"
change="list1_changeHandler(event,List(event.currentTarget).selectedItem)" x="103" y="77" height="350" width="198"/>
That was my goal to do that with the database.
Please help me
If you have other solution I still need it.
Thank you,

ADF: Display image from database

Hi,
I've found a number of threads addressing this issue, but none that have solved my problem as yet. I'm trying to display an image from a database column in JDev 10.1.3.2.0. I've found an article in the Help that sounds like it's describing exactly what I need:
To insert a databound image control into a form or panel: In the ADF Swing project, open the Java Visual Editor on the desired data panel or form. From the View menu choose Data Control Palette to open the palette. In the Data Control Palette, drag the attribute you want to bind to the image control into the open form or panel. From the Add Child popup list, select JUImageControl. JDeveloper adds code to the class file to bind the JUImageControl to the attribute
The problem I'm having is that this doesn't bear any relation to what I can see. I'm presuming that the Java Visual Editor is the design tab of the jsp page editor, as this is the only visual editor I can find. If it isn't, that would explain why this doesn't work... When I drag my attribute, I have to select what type of item I want it to be. I can't find an Add Child popup anywhere.
I have a horrible feeling that this is a very stupid question, but I'm completely stuck.

The help-text you found refers to an ADF-Swing project, not a web application with JSP's. This post: How to display the content of a BLOB column in a ADF/BC pages ? shows you how to do it with ADF Faces.

Display image from the save link in the field

Hi all,
I have a image link that saved in a column and will like this picture to be displayed once user is click on the image link in the tabular format.
However, now I am facing the problem to perform query of the record because one of the field type is image or ole. However, if I changed the image link to normal text item. I am able to perform query search on the record. My question is, can I click on the record whenever I want to see the image from the tabular form ? I prefer tabular form as I can see a lot of records in one sort. But for the image display, I will like user to clock on the specific link in order to open up the image.
Will this possible ?
Thanks
Lim

If you are saving the image path in table not the image then why don't you use the READ_IMAGE_FILE built-in (see forms help).
What i mean is hide the actual item which is having the image location. Just create one image item from toolbar (non-database) and create one extra button in the same block to display the image then use the READ_IMAGE_FILE built-in as below in WHEN-BUTTON-PRESS-TRIGGER...
READ_IMAGE_FILE(:path_item_name,NULL,'image_item_name');
Preferred way would be to save the image in database then query in your form using database image.

Also, there is no luck with displaying text content from a file, using printDoc
tag. Can some one point me to right resource.

Hi panji,
I used 7.0 tag lib, just to make use of "printDoc" tag which is available in 7.0version
only and not in 810. However, i figured out a way to display image using 8.1 (
of course, by using request.getContextPath() + "/ShowBinary" + imagedoc.getPath())
But still, i do not find a way to display a doc type file in jsp, which is my
original problem.
As per the edocs at http://edocs.bea.com/workshop/docs81/doc/en/core/index.html,
<cm:getProperty node="<%=doc_node%>" name="file"/>
should be able to display a txt file but nothing is getting rendred onto jsp.
( i have created a book type content in the repo. and file attached is of type
txt ).
Can you pls give some clue what i am missing here?
thanks

Displaying Image from ADF BC (BLOB Column) in ADF Mobile Application

I have made an ADF BC over a database. Now I want to use that ADF BC's data control in my ADF Mobile App to display image stored in a blob column in the database!
How should I got about it?
Regards,
Muhammad Zaheer

Sir,
I have exposed it through web services and I'm using the Web Service data control in my mobile application but the blob column is shown as output text in the data control. Now I don't know how to display the image from the blob column in my ADF mobile application.
Looking forward for your help.
Thank you.

Display Images from Database

Hi all,
I require to display images stored in database along with textual description of it on a JSP.
The image file should not be stored intermediately on file system (i.e w/o using img HTML tag)
It is a typical shopping cart appln. where images are fetched from database and the associated description is displayed along side.
Please note that it is the case of Mixed content types(text and binary data).
Thanks and Regards

Like "Breakfast" said, you can do this with a servlet that retrieves your images from a database....
if you create a servlet to do this, you would have a generic servlet which retrieves a picture from a database based upon a key which could be a picture name or number.
Lets say the file is out there in the database as a BLOB or Binary Image... you could have this kind of code in the doPost(HttpRequest req, HttpResponse res) or doService(HttpRequest req, HttpResponse res) method.
The table holding the image has at least two columns one called IMAGE which holds the binary image and the other called FILENAME. If the connection to the DB is already open, you do something like this.
String fileToGet = (String)req.getParameter("FILENAME");
rs = conn.createStatement().executeQuery("select from IMAGE_TABLE where FILENAME='" + fileToGet + "'");
if(rs.next())
InputStream in = rs.getBinaryStream("IMAGE");
res.setContentType("image/jpg"); // or whatever type of file it is.
ServletOutputStream sout = res.getOutputStream();
int c;
while((c = in.read()) != -1)
sout.write(c);
in.close();
sout.close();
This should write your image to the response output of the servlet.
Now, where you want your image, you put.
<img src="/servlet/ImageServlet?FILENAME="thefileIwant">
This should do what you want... Use your favorite pipe copy method to get the input stream to the output stream. If you are worried about overhead and scaling like "breakfast" said (it CAN be a problem in high access sites), then you can add an image caching scheme and get really complex.... But this is a rough idea on what to do.
Hope this helps.
